Answer: Choice C) 6x+5y = -20
You have the correct answer. Nice work.
=================================================
Work Shown:
y = (-6/5)x - 4
5y = 5*( (-6/5)x - 4 )
5y = 5*(-6/5)x - 5*4
5y = -6x - 20
6x+5y = -20
-----------
Explanation:
In the second step, I multiplied both sides by 5 to clear out the denominator. Two steps later (step 4), we have 5*(-6/5)x turn into -6x, so the fraction goes away.
In the last step, I added 6x to both sides to get the equation into standard form Ax+By = C. In this case, A = 6, B = 5, and C = -20.
